Unverified: "I published a story this morning about implants that have been discovered in a number of Ledger crypto devices." - Unverified: "In initial had included in the story information about implants that were also discovered in devices made by Trezor – Ledger's main competitor." - Unverified: "I removed this, however, before publishing the story because I didn't want to confuse matters." - Corroborated: "But a few hours ago Trezor announced on X that it would be reducing the number of merchants authorized to sell its devices out of an \"abundance of caution.\"" - Not auto-checked: "Chief Commercial Officer Danny Sanders wrote that there was \"not a single piece of evidence that Trezor devices have been compromised,\" and that this was reducing its list of authorized sellers simply as a \"preventive step\" to have better control over its supply chain." - Not auto-checked: "Famed hardware hacker Joe Grand found implants in two Trezor wallets recently." - Not auto-checked: "Famed hardware hacker Joe Grand notified the company about the implants in August." - Unverified: "I didn't include this in my Ledger story because the circumstances were different from the Ledger incidents." - Corroborated: "The Ledger implants became news." - Corroborated: "The Ledger implants were sold in devices distributed by authorized resellers of Ledger devices." - Unverified: "The Ledger implants were subsequently used to steal $100 million in crypto from the owners of devices that were compromised." - Unverified: "The Ledger implants became news because the implants were sold in devices distributed by authorized resellers of Ledger devices and were subsequently used to steal $100 million in crypto from the owners of compromised devices." - Unverified: "But as I noted in the Ledger story, Grand had initially found implants in four Ledger devices that were sold online by unauthorized Ledger merchants." - Unverified: "These merchants appeared to be fly-by-night sellers who popped up in online marketplaces only to disappear after days or weeks." - Unverified: "So the provenance of the compromised devices was already sketchy, as opposed to the later implants that were sold by reputable and authorized sellers." - Unverified: "The implants Grand found in Trezor One and Trezor Model T devices were also sold by third-party nonauthorized sellers – not by reputable authorized sellers." - Unverified: "No real surprise there, since both Ledger and Trezor have warned customers for years to purchase directly from their own web sites or from authorized merchants." - Unverified: "Especially because three years ago, researchers at Kaspersky Lab had also found an implant in a Trezor wallet sold on a popular Russian marketplace." - Not auto-checked: "Grand found an implant in a Trezor Model T wallet." - Unverified: "Someone had purchased the Trezor Model T wallet via Facebook Marketplace in Canada some time in 2025." - Unverified: "Grand found another implant in a Trezor One device." - Unverified: "Someone had obtained the Trezor One device from a TikTok shop in August." - Unverified: "The buyer of the Trezor One became suspicious when about $50 got transferred out of his crypto account." - Unverified: "The Trezor One is a discontinued device." - Unverified: "The Trezor Model T is a discontinued device." - Unverified: "Trezor still supports the Trezor One and Trezor Model T." - Unverified: "As noted in the product photo at top, Trezor will continue to distribute software updates for the Trezor One and Trezor Model T until 2031." - Unverified: "As noted in the product photo at top, Trezor will continue to distribute security updates for the Trezor One and Trezor Model T until 2036." - Unverified: "Customers still buy the Trezor One and Trezor Model T from third-party sellers." - Unverified: "In both wallets, the attackers had replaced the microcontroller on the devices so that instead of generating random recovery seed phrases, the controllers generated one of a dozen or so pre-determined seed phrases the attackers had coded into the controllers, allowing them to guess the recovery seeds for the crypto accounts." - Unverified: "Grand says the legitimate microcontrollers used in the Trezor devices have code-protection features that are meant to prevent someone from accessing and changing the code." - Unverified: "But because the Trezor code is open source, it was easy for the attackers to obtain the code, modify it, and program it into a new, unsecured device by just replacing the legitimate chip with their own chip." - Not auto-checked: "Grand says he wrote to Trezor about the Model T implant on August 10 this year and got a very cordial response three days later:" - Unverified: "Based on your description, the unit has very similar characteristics to the counterfeit or modified Model T devices that were discovered on Russian marketplaces in 2022–2023." - Unverified: "Although we have discontinued sales of the Model T, we continue to improve the checks in Trezor Suite that are intended to identify counterfeit and modified devices." - Unverified: "Notably, in his last communication from Trezor in early September, the company copied their pr manager on the email and told Grand, \"If you’re planning to publish something, we’d appreciate a heads-up so we can review it and, if appropriate, provide a public comment in advance as well.\"" Not auto-checked: this sentence names a private individual or small business, so no automated status is given.
